Running TestNG tests programmatically will discuss about how to execute TestNG tests programmatically.  Till now we have executed all the tests using testng.xml file in the previous videos. In this video, will see how to avoid xml file (i.e. testng.xml) and execute the same functionality using java file(i.e. programmatically).  

We have some limitations with the xml file that xml files are static and can not be changed at runtime. As per the requirement sometimes we need to change some of the configurations at runtime, which is depends on an Excel sheet or database data interaction. To achieve these kinds of things TestNG provided a feature to define and execute TestNG tests through program by using some of the APIs provided by the TestNG.

All the things which is possible with the testng.xml file can be achieved by the API provided by TestNG. And after completion of writing the program we can easily execute the code as this is a normal java file.
